Entrez Gene Summary for COL6A2 Gene

This gene encodes one of the three alpha chains of type VI collagen, a beaded filament collagen found in most connective tissues. The product of this gene contains several domains similar to von Willebrand Factor type A domains. These domains have been shown to bind extracellular matrix proteins, an interaction that explains the importance of this collagen in organizing matrix components. Mutations in this gene are associated with Bethlem myopathy and Ullrich scleroatonic muscular dystrophy. Three transcript variants have been identified for this gene. [provided by RefSeq, Jul 2008]

Ullrich congenital muscular dystrophy (UCMD) [MIM:254090]: UCMD is a congenital myopathy characterized by muscle weakness and multiple joint contractures, generally noted at birth or early infancy. The clinical course is more severe than in Bethlem myopathy. {ECO:0000269 PubMed:15563506, ECO:0000269 PubMed:15689448}. Note=The disease is caused by mutations affecting the gene represented in this entry.

Myosclerosis autosomal recessive (MYOSAR) [MIM:255600]: A condition characterized by chronic inflammation of skeletal muscle with hyperplasia of the interstitial connective tissue. The clinical picture includes slender muscles with firm woody consistency and restriction of movement of many joints because of muscle contractures. Note=The disease is caused by mutations affecting the gene represented in this entry.
